I've highlighted a few things that you might want to correct/rephrase.
Although Vincent sold only one painting out of all his works; (punctuation) even after his death he carried on his artistic ability (rephrase. He's dead. )The Starry Night by Van Gogh was his most famous painting out of all his works. In June 1889 he competed a peace called Hospital of Saint-Remy. This made his work more famous because of the way it caught people’s eye. (fn5) The viewer’s eyes move all over the picture rather than being focused in one spot. Everything about it including it’s color, texture, and lines he used very well in his artwork. The motive behind this was in memory of Gauguin and Bernard, Parisian artists, his friends. (fn4) Many ideas and colors influenced by the place where he shot himself. He did this (what?) in Auvers, and his surroundings when he was in the hospital. (fn2, fn3, fn4) He confined himself in a room, so his painting pictures were inspired by his own imagination. Vincent van Gogh is very well known for his creativity and his famous, crazy act of cutting off part of his ear. (fn2)
